I'm in the process of mounting a manual dual master cylinder (just removed the booster because it was too big). I found a bracket that the cylinder bolted onto with a hole in the middle. When the bracket is verticle the the booster is on a 45 degree angle but when I place it on the edge of the crossmember it is perfect. The booster levels out and all I need to do it do a little grinding and weld it on. Will this master cylinder power disc brakes? It came off a '73 Ford Ranchero with 11" discs. I think I will steal the porpotional valve too. I still need to find out if this bracket is still needed for something else.

 

Nathan, I think you answered your own question. If the donor car had disc brakes, there's no reason it won't work with them again. You will have to use the prop valve, though.

 

I just wanted to be sure since I will not be using the booster part of the setup. I will use the porportinal valve.
